Find (View) Active Zones in Firewalld on CentOS 7

Pre-Flight Check

• These instructions are intended for finding (viewing) active zones in Firewalld on CentOS 7 via the command line.
• I’ll be working from a Liquid Web Core Managed CentOS 7 server, and I’ll be logged in as root.

All network interfaces exist within a zone. They can be located in the default zone or split into other zones. Zones enhance an administrator’s capability to define trusts and restrict network traffic.
